CiviCRM release notes
Here's a neat little resource that the city CRM project started publishing recently:
A convenient list of all releases, with release notes for each, at https://download.civicrm.org/release/
This is no earth-shaking development. Release notes have always been publicly available. This just makes them a little easier to find.
And when you're deciding whether to upgrade — and to which version to upgrade — the release notes are a great resource.
I hope you'll use them to stay informed in deciding your upgrade strategy.
All the best,
A.
